The crew of China Wave Shipping Co., Ltd. does not belong to the establishment. There are two kinds of crew members, one is the official staff of the state-owned shipping company, and the other is the free crew. State-owned shipping companies, in order to change the development mode, recruit a large number of free crew members at the same time. At first, they mainly recruited ordinary crew members, and now they recruit senior crew members. However, most joint ventures and private shipping companies recruit crew members in the market.
